These sauces delight the adventurous, heat-seeking cook because they add zip and intensity to the dish. In the realm of hot ingredients, the chilli pepper wears the crown, but other interesting hot flavourings, such as mustard seeds, horseradish root, and fresh ginger, also have an important part to play in spicing up sauces. The heat in the chilli peppers, provided by capsaicin, helps with the process of thermogenesis, helping your body convert fat into heat, thus burning fat and resulting in weight loss.
